>Organization:
Orbitel JSCo.
>Environment:
System: FreeBSD ringworld.oblivion.bg 4.3-RC #50: Sun Apr 15 21:11:57 EEST
>Description:
/usr/bin/fstat does not recognize DTYPE_FIFO, and either ignores such fd's,
or, if invoked with '-v', complains about unknown file types.
>How-To-Repeat:
Plain vanilla 4.3-RC /usr/bin/fstat..
[root@ringworld:v0]# fstat -v 2>&1 | awk '($7=="6" && $10=="368") {print}'
unknown file type 4 for file 6 of pid 368
After applying the attached patch..
[root@ringworld:v0]# ./fstat -v 2>&1 | awk '($3=="368") && ($4=="6") {print}'
root supervise 368 6 /usr 583875 prw------- 0 r
>Fix:
Against -current, applies with a negligible offset to -stable..
